Struct GraphStore 

pub struct GraphStore { /* private fields */ }

In-memory graph store.

Implementations

impl GraphStore

pub fn new() -> Self

pub fn with_data_dir(data_dir: Option<PathBuf>) -> Self

pub fn create_node(&self, label: &str, properties: Value) -> GraphNode

Create a new node.

pub fn create_edge( &self, source: &str, target: &str, relationship: &str, ) -> Result<GraphEdge, String>

Create a new edge between nodes.

pub fn get_node(&self, id: &str) -> Option<GraphNode>

Get a node by ID.

pub fn delete_node(&self, id: &str) -> Result<(), String>

Delete a node and its edges. Lock order: nodes first, then edges (consistent with create_edge).

pub fn delete_edge(&self, id: &str) -> Result<(), String>

Delete an edge.

pub fn list_nodes(&self) -> Vec<GraphNode>

List all nodes.

pub fn list_edges(&self) -> Vec<GraphEdge>

List all edges.

pub fn get_all(&self) -> (Vec<GraphNode>, Vec<GraphEdge>)

Get all nodes and edges.

pub fn find_by_label(&self, label: &str) -> Vec<GraphNode>

Search nodes by label.

pub fn get_edges_for_node(&self, node_id: &str) -> Vec<GraphEdge>

Get edges for a node.

Trait Implementations

impl Default for GraphStore

fn default() -> Self

Returns the “default value” for a type.
